mbedtls_ecdh_get_params() function

The ECDH context to set up. This must be initialized.

The EC key to use. This must be initialized.

Defines the source of the key. Possible values are: - #MBEDTLS_ECDH_OURS: The key is ours. - #MBEDTLS_ECDH_THEIRS: The key is that of the peer.

This function sets up the ECDH context with the information given. This function should be called after mbedtls_ecdh_init() but before mbedtls_ecdh_make_params(). There is no need to call this function before mbedtls_ecdh_read_params(). This is the first function used by a TLS server for ECDHE ciphersuites.

This function derives and exports the shared secret. This is the last function used by both TLS client and servers. \see ecp.h

This function frees a context.

This function generates an EC key pair and exports its in the format used in a TLS ServerKeyExchange handshake message. This is the second function used by a TLS server for ECDHE ciphersuites. (It is called after mbedtls_ecdh_setup().) \see ecp.h

This function parses the ECDHE parameters in a TLS ServerKeyExchange handshake message. \see ecp.h

This function generates a public key and exports it as a TLS ClientKeyExchange payload. This is the second function used by a TLS client for ECDH(E) ciphersuites. \see ecp.h

This function parses and processes the ECDHE payload of a TLS ClientKeyExchange message. This is the third function used by a TLS server for ECDH(E) ciphersuites. (It is called after mbedtls_ecdh_setup() and mbedtls_ecdh_make_params().) \see ecp.h

This function initializes an ECDH context.

Print a field of the ECDH structure in the SSL context to the debug output. This function is always used through the MBEDTLS_SSL_DEBUG_ECDH() macro, which supplies the ssl context, file and line number parameters. \attention This function is intended for INTERNAL usage within the library only.
